Linux Redhat 7 下 Docker 离线安装部署
Docker安装前要
Docker官网：
服务器版：https://docs.docker.com/engine/install/#server
Docker 离线二进制tgz压缩包下载地址：
https://download.docker.com/linux/static/stable/x86_64/
例如：
docker-23.0.6.tgz
Docker 离线rpm包下载地址：
https://download.docker.com/linux/centos/7/x86_64/stable/Packages/
Docker安装步骤
- 确定OS系统环境，CentOS 7/Redhat 7及以上版本
|
[root@test soft]# cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.9 (Maipo) [root@test soft]# uname -a Linux test 3.10.0-1160.el7.x86_64 #1 SMP Tue Aug 18 14:50:17 EDT 2020 x86_64 x86_64 x86_64 GNU/Linux [root@test soft]# |
2、卸载旧版本
|
[root@test soft]# ps -ef|grep docker root 3866 3625 0 09:12 pts/0 00:00:00 grep --color=auto docker [root@test soft]# [root@test soft]# yum remove docker \ > docker-client \ > docker-client-latest \ > docker-common \ > docker-latest \ > docker-latest-logrotate \ > docker-logrotate \ > docker-engine Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager This system is not registered with an entitlement server. You can use subscription-manager to register. No Match for argument: docker No Match for argument: docker-client No Match for argument: docker-client-latest No Match for argument: docker-common No Match for argument: docker-latest No Match for argument: docker-latest-logrotate No Match for argument: docker-logrotate No Match for argument: docker-engine No Packages marked for removal [root@test soft]# |
- 下载离线安装包，上传至服务端并解压
|
[root@test soft]# tar -zxvf docker-23.0.6.tgz docker/ docker/docker-proxy docker/containerd-shim-runc-v2 docker/ctr docker/docker docker/docker-init docker/runc docker/dockerd docker/containerd [root@test soft]# |
- 将解压后得到的二进制文件全复制到/usr/bin目录下
|
[root@test soft]# cp docker/* /usr/bin/ |
5、将docker注册成系统服务,修改" vi /etc/systemd/system/docker.service " 内容（没有的话vi命令会自动创建该文件）;
注意:配置需要注意的是 ： ExecStart=/usr/bin/dockerd，代表dockerd所在位置

- 增加文件可执行权限
|
chmod +x /etc/systemd/system/docker.service systemctl daemon-reload |
- 设置开机自启动
|
systemctl enable docker.service systemctl status docker.service ##systemctl disable docker.service |
- 启动docker
|
systemctl start docker ##systemctl stop docker |
- 测试
|
docker ps |
如果打印出如下信息，则表示正确安装：
[root@test soft]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
[root@test soft]#
